WASTE-PIPE-CLEANING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 576,507, dated February2, 1897. Application filed January 10, 1896. Serial lilo. 575,042. (Nomodel.)

To all w/Lom/ it may concern/.-

Be it known that I, WILLIAM A. McCLnL- LAND, a citizen of the UnitedStates, residing at Kansas City, in the county of Jackson and State ofMissouri, have invented certain new and useful Improvements inWaste-Pipe-` Cleaning Apparatus; and Ido hereby declare that thefollowing is a full, clear, and exact description of the invention, suchas will en able others to make and use the same, reference being had tothe accompanying drawings, forming a part-of this speciiication.

The objects of my invention are, first, to employ the hydraulic force ofa stream of water under pressure in connection with the receiver for thecleaning of waste-pipes; second, to adapt the apparatus to waste-pipesvarying in diameter.

My invention consists in the novel construction and combination ofparts, such as will first be fully described, and specifically pointedout in the claims.

In the drawings,Figure lis a view in perspective of my improvedwaste-pipe-cleaning apparatus with the water-supply pipe, also showing asink, with a portion of the side of the sink removed, and the apparatusapplied to the waste-pipe. Fig. 2 is a horizontal side view of theapparatus,shown connected with a street waste-pipe and with the apronclamped to the pipe. Fig. 3 is a Vertical sectional view in detail,showing the elastic receiver within the waste-pipe, the apron and clamp,and the hollow handle connected with the receiver. Fig. 4 is a detailview of the apron.

Similar letters of reference indicate correspending parts in all theiigures.

Referring` to the drawings, Arepresents the elastic receiver, whichconsists of an inverted cupmade of rubber and conforming exteriorly tothe figure of a cone. In the apex a of the receiver A is a threadedopening eX- tending in the direction of the axis of the receiver, inwhich opening` is iitted the screwthreaded end b of the hollow tubularhandle I5. The tube B is made short in length, and

the other end Z2 of said tube is internally screw-threaded, and to saidend is fitted the screw-thread end c of an extended portion of thehandle C, which is made up of wood and closes the end Z9 of said pipe B.In the side of tube B near the end portion of the handle C is an openingb2. To the outer side of said tube, around said opening, is attachedrigidly one end d of a Water-conducting pipe E, which is bent at anangle in close position to the sides of the tubular handle B,and theother end of said pipe is extended in a vertical direction, and in saidend is a back-pressure valve e. To said upper end dIV of pipe E isattached by a union-coupling f one end of a rubber or elastic hose F,the other end of which hose is connected with the water-supply pipe G ofa street water-supply system.

On'the base F is an elastic collar or spool II, upon which is a clamp h,which clamps the end of the hose F to the water-supply pipe G nearspigot g. On the tube B, a short distance above the point of attachmentwith the receiver A, is a disk Z, upon the upper side of which disk is asleeve t', which extends around pipe B. The said disk Z and sleeve t',which are in one piece, are also for the purpose of removal cast in twoparts in a vertical direction, and upon the said disk are lugs '17,opposite in position, which are provided with securing-bolts t2. Uponthe separate parts of sleeve t" are lugs i3, opposite in position, whichare provided with securing-bolts t4.

For the purpose of cleaning Waste-pipes, such as pipe M, leading to thesewer and larger drain-pipes, the connections are removed, so as toexpose the upper open end of the pipe, over which is placed a rubbergasket L, to the outer edge portion of which is connected a circularapron Z, the apron and gasket being made in one piece. The receiver A,which is nearly of the same diameter as the pipe M, is inserted withinsaid pipe, the apron Z extending around the outer side portion of saidpipe. Aclamp N, in two separate parts, is itted over the apron Zandaround the said end portion of said pipe, which parts of said clamp areprovided with lugs n n and secured by the bolts n. Upon the separateparts of the clamp A are lugs n3, which extend over the edge of the diskZ and hold the disk in position.

In the operation of the apparatus the receiver A is placed within thesink K and eX- tending around the Waste pipe aperture. The operatorseizes the handle C with both hands and bears downwardly with sufficientIOO force to compress the receiver A, which contains air, and the sidesexpand and drive the air forcibly through the waste-pipe. The pressureis then released from handle C and the elasticity of the receiver causesa reverse movement. The spigotg is then turned so as to admit the flowof water from the sewage-pipe G under pressure, which iiows through hoseF, pipe D, into the tube B and receiver A, thence to the waste-pipe, thereceiver A filling rapidly and containing an eX- cess of water which isabove the opening to the waste-pipe. Pressure is then applied to thehandle C downwardly, and this action causes the receiver to yield andforce the water within its sides through the waste-pipe with greatforce, the return of the water up the pipe B and CZ being checked by thebackpressure Valve e. The pressure is then released upon the handle C,and the receiver is expanded again with water and the movement upwardand downward of the handle C continued alternately, forcing the waterwith great force through the waste-pipe and cleaning the sides of thepipe thoroughly and effectively,the water receiving an impetus si milarto that effected by the action of a hydraulic ram and carrying out ofthe pipes all waste obstructions.

In the cleaning of waste-pipes, as shown in Figs. 2 and 3, the handle isoperated in the same manner, the surplus water in the pipes receivingthe pressure of the water passing through the receiver under pressure.

Having fully described my invention, what I now claim as new, and desireto secure by Letters Patent, is-

1. In a waste-pipe-cleaning apparatus, consisting of an invertedelasticcup, and a handie connected with said cup, the combination of apipe-closing cover extending around said 4o handle, substantially asshown and describedf 2. In a waste-pipe-cleaning apparatus, the

combination with the waste-pipe of an inverted elastic cup, a handleconnected with said cup, a pipeclosing cover extending 45 around saidhandle and a gasket between said cover and said Waste-pipe having anapron extending around said pipe, substantially as and for the purposedescribed.

3. In a waste-pipe-cleaning apparatus, the 5o combination with thewaste-pipe of an inverted elastic cup, a handle connected with said cup,a disk on said handle and a gasket between said disk and waste-pipe,having an apron extending around said pipe, and a clamping device forsaid apron, substantially as shown and described.
